PixiJS 2D Renderer

PixiJS is an open-source 2D rendering engine for the web that provides hardware-accelerated graphics through WebGL and WebGPU, enabling high-performance rendering of sprites, graphics, text, and filters for games, interactive experiences, and data visualizations. Created by Mat Groves in 2013 and now maintained by Goodboy Digital, PixiJS can render tens of thousands of sprites at sixty frames per second by leveraging GPU acceleration through batch rendering, texture atlases, and render texture caching. The rendering pipeline includes a stage container hierarchy for organizing display objects, an application loop with ticker for frame-by-frame updates, and a renderer that automatically selects between WebGL and WebGPU based on browser support. PixiJS supports sprite sheets and texture atlases for efficient asset loading, graphics primitives for drawing shapes, meshes for custom geometry, particles for visual effects, and a filter system for applying shaders including blur, color matrix, displacement, displacement, and noise effects. The event system handles pointer interactions with hit testing, and the loader manages asset preloading with progress tracking. PixiJS is used in production by game studios, advertising agencies, and interactive media companies, and serves as the rendering engine behind libraries including ReactPixi, Basis, and several HTML5 game frameworks.
